Kael shouldn't have gone.
He knew that.
Which meant going was about more than information.
The abandoned helix substation beneath the Lower Spiral was colder than he expected. Not temperature — atmosphere. It carried the weight of old ambition. Machinery that had once powered something important, now silent.
Selene stood in the dim light like she belonged there.
"You came alone," she said.
"I don't bring witnesses."
"You brought doubt."
He didn't react outwardly, but the observation hit.
"You're speaking in riddles."
"No. I'm speaking in truths you don't want framed."
She circled slowly, keeping distance but studying him carefully.
"You're angry at them."
"I'm not."
"You are."
Silence.
"You were raised as the heir, but never felt it settle in," she continued. "They praised you publicly and questioned you privately."
He didn't deny it.
"That's how aristocracies maintain control," she added.
"You attacked a school."
"We disrupted indoctrination."
"You destabilized civilians."
"They were safe."
"They were lucky."
Her eyes sharpened slightly.
"You're more protective than I anticipated."
He stepped forward.
"You tested me."
"Yes."
"You wanted to see if I'd survive."
"I wanted to see if you'd surpass."
A faint rumble shook the upper platform.
Kael's gaze flicked upward.
"You brought an audience."
She didn't deny it.
Three Null operatives descended in fluid motion.
Not charging.
Observing.
Testing perimeter.
One triggered a low-frequency pulse.
Kael felt it ripple through his bones.
Instead of resisting—
He adjusted.
He mimicked structural reinforcement.
Then layered density modulation.
Then refracted vibration across the wall behind him.
It wasn't mimicry anymore.
It was synthesis.
Selene's expression shifted — satisfaction, yes, but something else too.
Recognition.
And then—
Lyra's voice echoed down the tunnel.
"WHY IS IT ALWAYS A BASEMENT??"
She slid down a railing, hit the ground poorly, recovered quickly.
She took one look at the operatives.
"Oh good! Henchmen."
Kael stepped forward instinctively, shielding her.
One operative lunged.
Lyra panicked and smacked a control panel blindly.
A resonance surge destabilized the ceiling.
Concrete cracked.
Selene reacted instantly, redirecting the collapse away from them.
Kael hardened fully and absorbed falling debris.
Dust filled the air.
When it cleared—
Lyra blinked up at him.
"…So. Field trip?"
Kael looked at Selene through the haze.
"You endangered her."
Selene's expression didn't shift.
"No. I observed you."
That chilled him more than the attack.
He realized then—
She didn't see people.
She saw variables.
